Indications for Use
The Bladder Scanner (model: PadScan Z3, PadScan Z3, PadScan Z5) projects ultrasound energy through the lower abdomen of the patient to obtain images of the bladder which is used to calculate bladder Volume noninvasively. The Bladder Scanner is intended to be used only by qualified medical professionals.
Device Story
Handheld, battery-operated B-mode ultrasound device; projects ultrasound energy through lower abdomen to image bladder; calculates bladder volume noninvasively. Operated by qualified medical professionals in clinical settings. Features two operation modes (Expert/Easy), touch screen, and thermal printer. Provides real-time pre-scan imaging; outputs bladder volume and images. Data can be uploaded via USB or Bluetooth. Benefits include fast, non-invasive, and reliable bladder volume assessment, aiding clinical decision-making regarding urinary retention or catheterization.
Clinical Evidence
No clinical data. Substantial equivalence supported by non-clinical bench testing, including electrical safety (IEC 60601-1), electromagnetic compatibility (IEC 60601-1-2), acoustic output (NEMA UD 2), and biocompatibility (ISO 10993-1, 5, 10).

Connectivity via USB/Bluetooth. Class II equipment, Type B applied part. Standards: IEC 60601-1, IEC 60601-1-2, IEC 60601-2-37, NEMA UD 2.
Indications for Use
Indicated for non-invasive bladder volume calculation in patients via B-mode pulsed-echo ultrasound. Contraindicated for fetal use, pregnant patients, patients with ascites, patients with open/damaged skin, or wounds in the suprapubic region. Intended for use by qualified medical professionals.
Regulatory Classification
Identification
An ultrasonic pulsed echo imaging system is a device intended to project a pulsed sound beam into body tissue to determine the depth or location of the tissue interfaces and to measure the duration of an acoustic pulse from the transmitter to the tissue interface and back to the receiver. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.
Special Controls
*Classification.* Class II (special controls). A biopsy needle guide kit intended for use with an ultrasonic pulsed echo imaging system only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.
